This version bumps the ssh2 dependency to 1.5.0.

This version also changes the handling of options passed into put() for the internal write stream used to create the remote file. It is now no longer possible to set the write stream to autoClose: false. This caused a RCE problem because the promise was resolved on finish rather than close, which could result in false 'file not found' errors. As autoClose: false is of little benefit for this internal write stream and as there is no easy way to manually close the stream when autoClose is false, having this ability causes more problems than it solves. Now, any setting of autoClose on the write stream will be ignored (it is always autoClose: true). As this is an interface change, bumping to v7.1.0
